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. These analyses contribute to the continuous improvement of the production process and product design. This paper presents typical macrofractographic and microfractographic aspects of fatigue failures of cast aluminum components. As […]

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

Tokyo, October 15, 2003 – To a “Do cars excite you ?” theme, Mitsubishi Motors Corporation (MMC) will be showing a number of concept cars, new-generation engine family and other technology, rally machines and current production models as it explores a new emotional relationship between man and machine at the 37 th Tokyo Motor Show.
