99% and the grain size of 53 Km were chosen as raw materials, and were put into ball milling vessels. Af- ter evacuating the vessels and back filling with argon to prevent oxidation, the powders were milled in a. QM-ISP planetary ball miller. The balls are GCr15 bearing steel with the diameter of 10 mm. The rotar tion velocity...

Synthesis of TiC Powder by Mechanical Alloying of Titanium and ...

chanically alloyed in a QM-ISP planetary ball mill at ambient temperature. The powders (5g) were mixed and sealed in a stainless steel vial (500ml capacity) under an argon atmosphere. The mass ratio of ball to powders was 50︰1. Two kinds of hardened steel balls of ϕ 20mm and ϕ 6mm diameter were selected. The.

Hydrolysis of ball milling Al–Bi–hydride and Al–Bi–salt mixture for ...

May 25, 2007 ... size is approximately 13 μm and the powder size of other materials is confined in 100–300 μm. The composites were mixed in an argon-filled glove box. Then ball milling was performed by QM-1SP planetary ball miller under 0.2–0.3 MPa argon atmosphere. Ball-to-powder mass ratio corresponds to 30:1.

Effect of Particle Size on the Microstructure of ... - Atlantis Press

chemical composition configuration alloy, alloy weight is about 5-10 g. In a typical run, copper powder was mixed with chromium (40 at.%), and the mixture was placed in a 25ml stainless steel container and milled in a QM-1SP type planetary high energy ball mill, with argon for 48h, 36h and 60h. Stainless steel balls of 8mm...
