3 IMR KINKEN Research Highlights 2012 IMR KINKEN Research Highlights 2012 To reduce the fuel consumption by automobiles, medium carbon steels for forging parts, such as shafts and connecting rods, must be further strengthened. When carbide-forming elements such as Ti, Nb, and V, are alloyed with carbon steels, a fine dispersion of alloy carbides and large precipitation hardening can be achieved...

Local strength of friction stir (FS) welds and FS processed aluminium alloys in heat treatable aluminium alloys is dominated by precipitation hardening. Strengthening due to stored dislocations is generally limited to 40MPa, and grain size strengthening is generally less than 10MPa. Local crystallographic texture can cause yield strength variation on the order of 5%. Published models for streng...

Aluminum alloy 6201 is a wrought, heat-treatable alloy, which used in electricity transmission and distribution lines. The processed commercial continuous casting rolling system, includes series of in-line thermomechanical processes involving hot working, quenching, cold working artificial aging. In this study following the subjected to solution heat treatment at 510 °C for an hour, quenched ic...
