Precipitation hardening is one of the most frequently used methods post-processing heat treatments 3D printed tool steel 1.2709, as it increases yield and ultimate tensile strengths steel. Within this work, broad temperature range 250°C – 550°C was tested with five differ-ent holds at each to study effect processing parameters on microstructure mechanical properties. Maraging 1.2709 pro...

Maraging steels are high-strength that hardened by the formation of precipitates during an isothermal aging heat treatment. Depending on temperature and time cooling rate after holding can play a significant factor development microstructure mechanical properties. This study seeks to show how influences precipitation hardening effect, austenite reversion hardness impact toughness. The material ...

The quality of built parts by selective laser melting (SLM) relies on the comprehension phenomena that takes place during and solidification metal powder. scattering spatter particle as liquid SLM process affects layer consolidation powder bed in addition to surface part. present study is focused behavior maraging steel achieve a thorough understanding occur fusing particles are tracked using h...

The effect of long-term ageing (1000, 2000, and 3000 h) at 475 °C on mechanical properties, microstructure, substructure CUSTOM 465® maraging stainless steel was studied. additional precipitation nanometric particles ?-Ni3Ti phase in partly recovered lath martensite decomposition the BCC solid solution accompanied by formation Cr-rich ?’particles were identified. fraction reverted austenite fin...
