Resistance spot welding technologies of high strength steel (HSS) sheets were investigated in order to get high reliability in welded-joints of automobile components. Suitable welding current range shifted to lower currant side by the effect of electric resistance increase of steel sheet and the width of this range was affected by electrode force. Vickers hardness [...]

A well-established knowledge of the fractographic characteristics of cast alloys is required to perform fracture analysis of failed components and to determine their fracture mechanisms. It can also be used to validate related claims on car insurance coverages. These analyses contribute to the continuous improvement of the production process and product design. This paper presents [...]

Mercedes Benz have unveiled their all new Mercedes Benz SLR McLaren supercar at the Frankfurt Auto Show. The car was a joint project between Mercedes Benz and their Formula 1 partner McLaren, which has no doubt resulted in the adaptation of several racing technologies into the high performance road going sports car. Further evidence of [...]

The term “heat treating” for aluminum alloys is frequently restricted to the specific operations employed to increase strength and hardness of the precipitation-hardenable wrought and cast alloys. These usually are referred to as the “heat-treatable” allo
