“…On the other hand, W or Ni based intermetallic compound (such as W5Si3, NiTi etc.) or WC contamination was not identified after sintering at 1400 ºC, as shown in Figure 3: These phases have been already reported for the sintered W matrix composites reinforced with carbide/boride and oxide particles [12,19,20]. The present result can be attributed to the proper amount of the reinforcement (2 wt.…”

“…have been used in order to improve the properties of W based composites [58]. However, addition of transition metal diborides as well as oxide particles is not a considerably discussed topic since only one study reported the eects of Y 2 O 3 and TiB 2 particles [9]. The aim of the present study is to report the eects of TiB 2 and La 2 O 3 particles on the microstructural and physical properties of WNi matrix.…”

“…[6,[13][14][15], oksitler (Y2O3, La2O3, HfO2, ZrO2, vb.) [5,6,12,[13][14][15][16][17][18] gibi takviye elemanları kullanılarak çalışmalar yapılmaktadır. Bu malzemeler arasından, TiB2, yüksek ergime sıcaklığı, yüksek sertlik, yüksek aşınma direnci ve iyi kimyasal kararlılığı nedeniyle öne çıkmaktadır [15,19,20].…”

“…Özellikle takviye edici malzeme olarak La2O3 kullanılmış çalışmalarda, La2O3'ün kompozitlerin düşük sıcaklıktaki kırılganlığını ve yüksek sıcaklıktaki aşınma miktarını azalttığı gösterilmiştir [11,18]. İki farklı takviye malzemesi kullanılarak üretilen W esaslı hibrit kompozitler ile ilgili çalışmalar da literatürde yer almaktadır: Bu çalışmalarda, W matrisinin özellikleri, W esaslı hibrit kompozitler oluşturularak daha da geliştirilmiştir [11,13,14].
