AB  - Bu çalışmada tozmetalurjisi yöntemiyle Fe matris içerisine sabit oranda grafit ve niyobiumilavesinin yanı sıra farklı oranlarda vanadyum elementinin (% Ağırlık olarak0-0,025-0,05-0,1-0,3-0,5-1-3) katılmasıyla istenilen bileşimde çelik malzemetoz karışım olarak elde edilmiştir. Elde edilen tozlar çekme numunesi şeklindetasarlanan kalıpta 700 MPa presleme basıncında sıkıştırılarak atmosferkontrollü tüp fırında argon atmosferinde 1400ͦC’de sinterlenerek çelik üretimigerçekleştirilmiştir. Farklı V oranlarına sahip Nb-V mikroalaşımlı çeliknumunelerin mekanik özellikleri çekme ve mikrosertlik testi ile analizedilmiştir. Toz metal çeliklerin mikroyapısı optik mikroskop ile karakterizeedilmiştir. Sonuçlar % ağırlık olarak % 1 V ilave edilmiş TM çelik numunelerinen yüksek akma ve çekme dayanımına sahip olduğu göstermektedir. V miktarı %1’dan %3’e çıkması ile akma veçekme dayanımında azalma gözlenmiştir.

N2  - In this study, the addition of vanadium element (0-0,025-0,05-0,1-0,3-0,5-1-3% by weight) at different ratios as well as the addition of graphite and niobium in the fixed matrix into the Fe matrix by powder metallurgy method the steel material in the composition is obtained as a powder mixture. The obtained powders were compacted at 700 MPa pressing pressure in the form of drawn specimen and steel production was performed by sintering at 1400 ° C in argon atmosphere in an atmosphere controlled tube furnace. The mechanical properties of Nb-V microalloyed steel specimens with different V ratios were analyzed by tensile and microhardness test. Microstructure of powder metal steels is characterized by optical microscope. The results show that the TM steelsamples added with 1% V by weight have the highest yield and tensile strength. With increasing the V content from 1% to 3%, a decrease in yield and tensile strength was observed.
