作者：BW Roberts，CD Hackett，DA Canonico 摘要：The weldability of thick sections of Modified 9Cr-lMo steel (Grade 91) has been investigated. The alloy has excellent fabricability. It is not susceptible to hot cracking on stress relief cracking. It is, as are most highly hardenable steels, susceptible to hydrogen assisted cracking but it can be avoided by good shop practice. A soft zone can occur in the heat-affected-zone which can result in Type IV cracking in service. …… 关键词：materials science chromium-molybdenum steels welding fossil-fuel power plants materials design fabrication fatigue gas tungsten-arc welding heat affected zone 年份：1992 |
