Abstract
The objective of this work is to elucidate the tensile behavior of sintered Ti compacts made from gas-atomized and HDH powders by Metal Injection Moulding (MIM) Process.
The results obtained were summarized as follows:
(1) Tensile strength increases almost proportionally to the amount of HDH powder in gas-atomized powder, relating strongly to oxygen content in sintered Ti.
(2) Tensile elongation is 20% constantly upto 50% (oxygen content 0.3%) of HDH powder to gas-atomized powder and then, rapidly decreases for more than 50%.
(3) Sintered Ti has better tensile strength (640MPa) and elongation (21%) in equal amount of HDH and gas-atomized powders, well compared to JIS 3 grade of wrought Ti.
