Abstract:

 This paper is a comparative study on mechanical properties, wear resistance and machinability behaviors of AM20, AJ21 and AS21 Mg-2Al-X cast magnesium alloys. The effects of the changing in third alloy component x:0.5 Mn, 1 Sr and 1 Si, and constant 2 Al, wt. in these alloys on microstructure intermetallic phases, mechanical and wear properties and machinability cutting force, surface roughness, FBU and also chip formation were comparatively analyzed. The highest mechanical properties and wear resistance were in AS21 i.e. 49.2 hardness and 181.5 MPa UTS alloy and the highest machinability were in AM20 cutting force 35.6N alloy. The machinability of the alloys were increase with increasing cutting speed.

 Bu makale, AM20, AJ21 ve AS21 Mg-2Al-X döküm magnezyum alaşımlarının mekanik özellikleri, aşınma direnci ve işlenebilirlik davranışları üzerine karşılaştırmalı bir çalışmadır. Bu alaşımlardaki üçüncü alaşım bileşenindeki x; 0,5 Mn, 1 Sr ve 1 Si ve sabit 2 Al, ağırlıkça  değişimin mikroyapı intermetalik fazlar, mekanik ve aşınma özellikleri ve işlenebilirlik üzerindeki etkileri karşılaştırmalı olarak analiz edilmiştir. Bu alaşımların mikroyapısında bulunan intermetalik fazların sertlik, mukavemet, aşınma direnci ve işlenebilirlik özellikleri kesme kuvveti, yüzey pürüzlülüğü, talaş yığılması-FBU ve ayrıca talaş oluşumu üzerinde etkisi olduğu görülmüştür. En yüksek mekanik özellikler ve aşınma direnci AS21 49.2 sertlik ve 181.5 MPa UTS alaşımındaydı ve en yüksek işlenebilirlik AM20 kesme kuvveti 35.6N alaşımındaydı. Alaşımların işlenebilirliği artan kesme hızı ile artmıştır.
