Sintering Behavior and Mechanical Properties of Ti–TiBw Composites Prepared with Pre‐alloyed Ti–TiBw Composite Powders
Source abstract
Abstract
Prealloyed powders present a promising alternative to traditional ball milling processes in powder metallurgy, addressing challenges such as uneven powder mixing and incomplete reinforcement reactions. This study investigates the preparation of Ti–TiBw composites using spark plasma sintering (SPS) at temperatures ranging from 950 to 1050 °C, utilizing Ti–TiBw prealloyed composite powders. The effects of sintering temperature on the microstructure and mechanical properties of Ti–TiBw composites are studied, comparing prealloyed composite powders with ball‐milled premixed powders. As a result, the composites exhibit excellent strength and ductility, with an ultimate tensile strength of 676 MPa at 1000 °C and an elongation of 20.42% at 1050 °C. Comparatively, Ti–TiBw composites prepared from premixed powders achieve densification at 1050 °C, 50 °C higher than those prepared from prealloyed powders.
