Discussion on the damage of metal powder to bus bar of insulation Al-smelting pots;

State-of-the-arts in metal powder rapid prototyping;

Application and Developmeat of ultrasonic in nanosized metal powder preparation;

Dynamical solidification characteristic of laser sintering metallic powder;

Study on laser scanning process of SLS for metallic powders;

The main metal powders of selective laser sintering (S LS) are introduced.

Preparing metal powders by the hydrogen reduction of insoluble compound slurries under high pressure is a new process compared with the arts of precipitating metal powders from corresponding metal salt solutions.

This paper describes that irregularly shaped metal powders were sphericized by using High Speed Airflow Impact Method Particles Composite System(PCS).

Despite the obvious advantage over common high alloy steel manufactured by cast-forge method,high alloy powder metal has not been put into wide application for some defects in manufacturing method and technology.
