A new method for producing higher density PM parts, high velocity compaction (HVC), was presented in the paper. Using water atomized pure iron powder without lubricant admixed as the staring material, ring samples were compacted by the technique. Scanning electron microscopy (SEM) and a computer con...

对由铁素体和渗碳体组成的低、中、高碳钢进行振动空蚀实验, 发现它们空蚀破坏的共同特点是铁素体的严重变形和破损. 但由于铁素体的含量及分布形态不同, 材料空蚀破坏的表现形式大不相同: 铁素体含量高的低碳钢以大面积均匀塑性变形为主; 铁素体含量与珠光体含量大致相等并呈网状分布的中碳(亚共析)钢是由于铁素...
