Section snippets Experimental. Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1. Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).

The demand for cuttingedge materials with a high strengthtoweight ratio and economic considerations is steadily increasing. Lightweight materials such as aluminium (Al) and its alloys are attractive, but some properties such as low thermal stability and high wear rate limit the application of aluminium alloys (AA) to some extent. Many researchers have developed various composites to get ...

Methods and procedures. A stainless steel bowl was loaded with 200 g Al and 4 vol.% of Al 2 O 3 powders with a balltopowder weight ratio of 5:1; meanwhile, to identify the effect of the nanoscale Al 2 O 3 reinforcements on the ballmilled composite powders, 200 g of Al without Al 2 O 3 was loaded into another stainless steel bowl. To prevent excessive coldwelding, 3 wt.% of stearic ...

Then the preoxidized titanium hydride powder was mixed with copper powder in a planetary ball mill. Both the jars and balls are made of stainless steel and balls of two sizes (10 and 5 mm) were used to obtain a better mixing effect. In the milling process, weight ratio of ball to powder and milling rate were fixed.
