Dr. Menzel's case was that of a woman aged forty-four, with marked congenital deformities of all the fingers and toes, except the right thumb, which was normal The right middle finger, at the middle of the first phalanx, and the right index finger, the middle of the second phalanx, were contracted by deep furrows, with enlargement of the part beyond the constriction in the former instance. On s...

Abstract Double-sided friction stir welding (FSW), performed with a pair of rotation tools, was studied in an attempt to increase the joining speed when applied automotive advanced high-strength steels (AHSS). The experiments were on butt joint 1.6-mm-thick 1180 MPa grade steel sheets, and sound welds obtained travel no more than 4 m/min, fairly comparable laser beam (LBW), one conventional pro...

Various solution-treatments were applied on a rapidly solidified and subsequently rolled Mg-7.50Al-1.07Ca-0.17Mn (mass%) alloy sheet, room-temperature stretch formability, tensile properties, microstructures, textures of the solution-treated sheets have been investigated. Although solution-treatment at 400 °C gives high strengths, sheet shows poor formability with Index Erichsen value 4.8 mm du...

High-temperature pre-stretching experiments were carried out on the AZ31 Mg alloy at 723 K with strain levels of 2.54%, 6.48%, 10.92%, and 19.2% to alter microstructure texture for improving room-temperature formability. The results showed that strain-hardening coefficient increased, while Lankford value decreased. In addition, Erichsen values all pre-stretch sheets enhanced compared as-receive...
