WebNov 27, 2024 · In order to measure the melting behavior of plasticized PLA crystallized at different temperatures, a first heating up to 200 °C was applied, followed by quenching at 50 °C min −1 to 0 °C; this allowed to avoid melt crystallization, thus obtaining a fully amorphous material. WebApr 25, 2024 · Crystallization of diamond in the Mg-Si-C system has been studied at 7.5 GPa and 1800 °C with the Mg-Si compositions spanning the range from Mg-C to Si-C end-systems. It is found that as Si content of the system increases from 0 to 2 wt %, the degree of the graphite-to-diamond conversion increases from about 50 to 100% and remains at …
