rocessing is new technology. GongXi steel or high carbon steel heating with small grain organization if before or during processing can form fine grain, is in (0.4 ~ 0. 6) melting temperature range, in a certain strain rate, has the ultra plastic.
The United States naval institute (NSP) to 5 2100 650 ℃ temperature steel processing test showed that, in the 650 ℃ under strain 2.5 dont happen really fracture. Therefore, it is possible to 650 ℃ temperature processing instead of high temperature
