Technological Problems of Closed- Die Forging of Powder Metallurgy Fe-Al Preforms
Source abstract
Abstract
Fe-Al PM preforms from powder mixes with 30 and 40at% Al were heated and closed-die forged at 500 or 550°C to yield materials with porosity lower than 10%. Brinell hardness, bend and compression strengths were determined, also after 4 h heat treatment at 540°C. The content of the Fe-Al intermetallics depends on forging temperature and heat treatment. Optimum bend strength reached, 153 MPa, was for 30%Al alloy, forged at 550°C and heat-treated. Larstran Shape program was used to simulate shape manufacturing by closed - die forging.
