英国纽卡斯尔大学冶金和工程材料系副教授、金属腐蚀专家D·哈迪先生应我所邀请于4月1～2日来我所讲学。讲学内容包括9个专题,涉及氢脆的一般原理、低合金钢的氢脆、高强度铝合金的氢脆和应力腐蚀开裂、铁合金的氢脆、铜合金的应力腐蚀等方面。我所和本市友邻单位科技人员共约百人听取了讲学并和哈迪先生展开了热烈的讨论。 Mr. D Hardy, an associate professor of metallurgy and engineering materials at Newcastle University in the United Kingdom, and a metal corrosion specialist, invited me to give lectures on April 1-2. The lecture consists of nine topics covering the general principles of hydrogen embrittlement, hydrogen embrittlement of low-alloy steels, hydrogen embrittlement and stress corrosion cracking of high-strength aluminum alloys, hydrogen embrittlement of ferro-alloys and stress corrosion of copper alloys. A total of about 100 teachers and technicians from our neighboring units listened to the lectures and started a lively discussion with Mr. Hardy.
