In rapidly evolving powder injection molding technology, the wide prevalence of various microstructures demands the powders of smaller particle sizes. The effects of particle size on the sintering behavior are critical to not only shape retention of microstructure but also its mechanical properties. This study investigates the effects of three different particle sizes on the sintering behavior of the 316L stainless steel (STS316L) samples, prepared by powder injection molding, via the dilatometry experiments. For this purpose, the STS316L powders of three different mean particle sizes, i.e., 2.97, 4.16, and 8.04 μm, were produced for STS316L. The samples for the dilatometry test were prepared through powder-binder mixing, injection molding, and solvent and thermal debinding. Dilatometry experiments were carried out with the samples in a H2 atmosphere at three different heating rates of 3, 6, and 10 K/min. The shrinkage data obtained by dilatometry experiments was collected and analyzed to help understand the densification and the sintering behaviors in terms of particles size and heating rate. The master sintering curve (MSC) model was used to quantify the effects of particle sizes. In addition, we investigated the microstructure evolutions in terms of particles sizes. © 2012 The Minerals, Metals & Materials Society and ASM International.

The particle size effect of 17-4 PH and 316L stainless steel powder was investigated for thepowder injection molding process. The mean particle sizes used were 8, 4, and 3 μm. Theparameters considered were solids loading, processing conditions and mechanical propertieswith respect to particle size. After a basic PIM optimization study, the investigation concernedmicro-features manufactured by means of the powder injection molding in terms of featuresize and dimensional consistency. The application is micro components for dental devices.

The microstructures of Zr-added Co-29Cr-6Mo alloy compacts fabricated with a metal injection molding (M1M) process and their metal release from the compacts immersed in 1% lactic acid were investigated for medical applications. The relationship between the niicrostructure and amount of Co released from the compacts is discussed phenomenologically. The relative density of the Co-29Cr-6Mo compacts increased when Zr was added to the powder with amounts of 0.03 and 0.1 mass% and sintered in Ar or N The amounts of Co released from the compacts containing 0.03 and 0.1 mass% Zr sintered in Ar or N were smaller than those from the other compacts. Therefore, the addition of Zr to the Co 29Cr-6Mo powders enhanced the sintering of the compacts and decreased the porosity in the resultant products, leading to the suppression of the Co release from the compacts. When the Zr-added Co-29Cr-ÓMo alloy powders were sintered in N2 the relative density of the compacts was smaller than that of those sintered in Ar. The powders were nitrided during sintering in N 2 and the nitrides disturbed the densification during sintering. In addition, a lamellar structure was formed in the Co-29Cr-óMo and Co-29Cr-6Mo-0.5Zr compacts. The amount of Co released from these compacts was larger than that released from the other compacts because local corrosion occurred at the interface between the different phases in these compacts during immersion in 1% lactic acid. In the MIM process, a small addition of Zr (less than 0.1 mass%) to the Co-29Cr- 6Mo alloy is effective for densification during sintering and suppression of the Co release from the compacts. © 2010 The Japan Institute of Metals.

Sintering of Zr pre-alloyed and water atomized 316L stainless steel powder for various content of Si was performed. The maximum sintered density was obtained at 0.8 mass% of Si for the powder pre-alloyed 0.05 mass% of Zr. Excess addition of Si -for example, 1.20 mass%- inhibited the densification by the growing of Sicontaining oxide particles. The pre-alloying of Si increased the ferrite content of powder but the correlation between the ferrite content and the level of densification was not observed. The 316L powder pre-alloyed 0.8 mass%Si and 0.05mass%Zr had finer grain size and this made a contribution to the densification by the volume diffusion.

2mass%Ni-Fe sintered parts are, at present, produced by premixed method using carbonyl iron powder and carbonyl nickel powder as principal raw materials. In this study, the production method of sintered parts using Zr pre-alloyed and water atomized 2mass%Ni-Fe alloy powder as raw material was investigated. Followings were observed; By pre-alloying with about 0.8 mass% of Si, Zr pre-alloyed 2mass%Ni-Fe alloy obtained the sintered density comparable to the conventional premixed method. The Si pre-alloying increased the surface energy of powder, and the activated surface diffusion, and thereby promoted formation of necks. The addition of carbon as alloying element obstructed the densification in lower sintering temperature, but, in higher temperature, promoted the densification by consuming oxygen with C-O reaction. The sintered parts of Zr and Si pre-alloyed 2mass%Ni-Fe alloy powder contained not only less pores and inclusions but also uniformly-sized grains. These resulted in higher values of tensile strength and hardness but lower elongation. By carburizing and quenching, the sintered parts of Zr and Si pre-alloyed 2mass% Ni-Fe alloy powder showed mechanical properties and hardness higher than those of the conventional premixed method. These values were controllable with adjusting of tempering temperature.

The main objective of the present work is to evaluate the effects of the addition of zirconium on the mechanical properties of Co-29Cr-6Mo sintered parts produced by metal injection molding process using water atomized powder as raw materials. The results are summarized as follows; l)The sintering density of Co-29Cr-6Mo alloy powder was increased by the addition of zirconium in both sintering atmosphere of argon and nitrogen. 2) Mechanical properties were also improved by the addition of zirconium in both sintering atmosphere of argon and nitrogen. By using MIM process, the products having better mechanical properties compared with casting method were obtained. 3) HIP treatment of sintering products increased the relative density by about 4% caused by diminishing pores. This densification produced the increase of tensile strength and 0.2% proof stress by about 100 MPa.

The main objective of the present work is to evaluate the effects of Zr addition on various properties of SUS316L stainless steel powders produced by water-atomization of liquid metals. The results are summarized as follows; 1 ) The sintering density of SUS316L stainless steel powders pre-alloyed with 0.05 mass% of Zr was about 2 percent higher than that of the powder containing no Zr. However, in the powder pre-mixed with 0.05 mass% of Zr, no effect of Zr addition was observed. 2) Mechanical properties were improved by pre-alloying with Zr, but impaired by pre-alloying with Zr. 3) In pre-alloyed powder with 0.05 mass% of Zr, the increase of sintering density to start from 1073 K was observed. The micro-structural observation showed that the neck formation between particles started at 1073 K. The temperature is lower by about 100 K compared with the powder containing no Zr.

Complex aluminium alloy components fabricated by powder metallurgy (P/M) offer the promise of a low cost and high strength-to-weight ratio, which meets the demands of the automotive sector. This paper describes the die compaction and sintering response of an atomised Al-6061 alloy powder containing Mg and Si produced by rapid solidification. A design of experiments is used involving three levels for each of the die compaction pressure, sintering temperature, peak temperature hold time and heating rate. Three trials were used to obtain the optimum press sinter processing conditions. Besides the mechanical properties, phase transformation and microstructure are investigated. Supplemental insight is gained through thermogravimetric analysis, differential scanning calorimetry and SEM with energy dispersive spectroscopy. Analysis of variation is used to quantify the contribution of each design variable to the mechanical properties. © 2011 Institute of Materials, Minerals and Mining.
