Abstract
To analyze the behavior of molybdenum powders during hot isostatic pressing (HIP) at sintering temperatures, microscopic modeling of plastic densification mechanisms, power-law creep and diffusion based on equations found byArzt et al. [Metallurgical Transactions (1983) 14A] was performed. The results show that at high temperatures (T> 0.5Tm, where Tm is the meltingtemperature) and pressures higher than 15Â MPa, high relative densities (D> 0.95) can be obtained by power-law creep and diffusion mechanisms, the former being more prevalent. HIP diagrams against temperature, pressure and time were plotted to describe densification mechanisms and were compared with literature values.
