Abstract: The progress and prospect on the sintering techniques of molybdenum and molybdenum alloys were summarized in this paper, including sintering theory, sintering equipment, and sintering processing parameters, and new sintering techniques. In the results, the sintering theory of molybdenum and molybdenum alloys still focuses on the traditional theory of powder metallurgy. The development of sintering technology is to obtain the fully densified, fine crystal, and homogenized sintered billets. The tendency of sintering technology is the closely combination of sintering equipment and tooling with new powder metallurgy technology, resulting in more cross-research. Fully densification, microstructure homogenization, fine crystallization, and precise shapes controlling of sintered complex shapes molybdenum products during the sintering processing of large molybdenum and molybdenum alloys billets will be the hot and difficult points on the studies of molybdenum and molybdenum alloys sintering techniques.
