| Abstract: | Ti powder compact was pressed through a high velocity compaction(HVC) machine,and the effect of lubricant content on properties of green compacts was studied by using US Instron 8802 Electrohydraulic Servo Mechanics Testing Machine to measure sample's compression strength,using JSM-6300LV scanning Electronic Microscope to observe fracture morphology of the compact,etc..The results show that a proper lubricant content can improve the maximum impact energy per mass in pressing Ti powder compact,and higher den... |
