Fatigue failure affects the majority of materials in various applications and is particularly detrimental to aluminium alloys which do not present a well-defined endurance capacity. With the growing use of aluminium castings in automotive industry and several other fields, it is important to compare the fatigue strength of components produced by different moulding processes. In this study, thin-walled components of aluminium A383.0 alloy were moulded using four industrial casting processes: die casting, vacuum die casting, squeeze casting, and permanent mould casting (gravity casting). Bending fatigue strength and tensile properties of the cast components were then compared according to their surface roughness and microstructural characteristics. © 2012 Elsevier B.V.

In order to achieve a fine uniform grain-size distribution using the process of thin slab casting and directing rolling (TSCDR), it is necessary to control the grain-size prior to the onset of thermomechanical processing. In the companion paper, Model Fe-Al Steel with Exceptional Resistance to High Temperature Coarsening. Part I: Coarsening Mechanism and Particle Pinning Effects, a new steel composition which uses a small volume fraction of austenite particles to pin the growth of delta-ferrite grains at high temperature was proposed and grain growth was studied in reheated samples. This paper will focus on the development of a simple laboratory-scale setup to simulate thin-slab casting of the newly developed steel and demonstrate the potential for grain size control under industrial conditions. Steel bars with different diameters are briefly dipped into the molten steel to create a shell of solidified material. These are then cooled down to room temperature at different cooling rates. During cooling, the austenite particles nucleate along the delta-ferrite grain boundaries and greatly retard grain growth. With decreasing temperature, more austenite particles precipitate, and grain growth can be completely arrested in the holding furnace. Additional applications of the model alloy are discussed including grain-size control in the heat affected zone in welds and grain-growth resistance at high temperature. © 2014, The Minerals, Metals & Materials Society and ASM International.

The effects of microstructure and texture on the toughness anisotropy of two API-X70 pipeline steels were investigated. One steel contained no nickel (0Ni) and the other contained 0.3 wt pct nickel (0.3Ni). Charpy V-notch impact testing was conducted on plate samples for both steels in three directions: longitudinal (L), transverse (T), and diagonal (D) with respect to the rolling direction. The microstructures of both steels were mixed and consisted of acicular ferrite, granular bainite, and small amounts of polygonal ferrite, with martensite-austenite and retained austenite islands as secondary phases. The ductile to brittle transition temperatures (DBTT) for the Charpy impact test were higher in the D direction for both plates, with a pronounced increase in the 0Ni steel. The anisotropy in toughness was mainly attributed to the crystallographic texture. © (2013) Trans Tech Publications, Switzerland.

Essar Steel Algoma Incorporation (ESAI) made several modifications and improvements to the processes at the No. 2 BOSP to ensure increased and sustainable production rate. The vessels at No. 2 BOSP are equipped with a nitrogen lance that allows slag splashing to prolong the life of the refractory brick. ESAI has a full-combustion hood system that generates steam used in other areas of the steel works. The facility would switch to performing approximately two relines per year, which allow faster tap-to-tap times and provide an extended maintenance window for the steam hoods. The increase in reline frequency would improve the proficiency of the masonry staff, and thus shorten the duration of the reline and its negative impact on production. The demands on the scrap yard also meant that the charge box fleet must be increased that allowed three charge boxes to be in active use that includes one in the shop for maintenance and two pre-filled with a standard charge to be used in emergencies.

ASME 2013 India Oil and Gas Pipeline Conference, IOGPC 2013 | Year: 2013
India is a large and rapidly growing economy. The energy requirements of the country in terms of oil products and natural gas is also huge. Given its vast geographical size, there is ever-growing need to transport these oil & gas products over large distances but economically. For this purpose, several new projects for laying of new pipe-line networks are at different stages of planning. In order to keep the cost of such large pipe-line projects lower, countries around the world have shifted to higher strength API grades of steel. This was facilitated by advances in steel-making and processing technology and modern facilities that came up in advanced countries. India is no different and we have seen a gradual shift towards higher strength API grades being used for pipelines. Essar Steel has been a major producer of API grades of steel in India over the last 15 years initially through its hot-strip mill and more recently adding a state-of-the-art 5M wide plate mill as well as pipe mills, both LSAW & HSAW. Different alloy designs have been used around the world to produce high strength and high toughness API grades. These have produced essentially two types of microstructures which are either ferrite + pearlite or ferrite + acicular ferrite. But these microstructures show varying response to the pipe-making process. Choice of alloy design also has a major bearing on the cost of steel, but is partly influenced by mill capability. At Essar, while cost was a major determining criterion for selection of suitable alloy design, mill capability was not a constraint. Essar Steel has successfully produced X-80 plates and pipes with a modified HTP alloy design and using the new facilities of plate mill & pipe mill. The paper gives some of the key highlights of this development activity. This was a collaborative effort between the metallurgists & engineers at Essar Steel India Limited and, experts from CBMM.
