摘要: Equal-channel angular pressing (ECAP) is an effective fabrication process for obtaining ultrafine-grained materials. This paper examines the development of homogeneity in materials processed by ECAP with emphasis on samples pure aluminum and Al-6061 alloy up to 8 passes at room temperature. The Vickers microhardness was recorded polished cross-sectional planes each as-pressed billet results are plotted form contour maps provide a pictorial depiction hardness distributions throughout cross-sections. factors influencing examined, including die corner angle within number imposed passes. It shown that good may be achieved through processing when reasonably high.
