Effect of Nb on microstructure and mechanical properties of chilled cast iron at room and elevated temperatures is studied in this research. The results demonst
With substitution of La by Tb in (La1-xTbx)0.67Sr0.33MnO3, the room temperature magnetoresistance AR/R0 drops at first, then undergoes an increase near x≈0.1,
The quantitative analysis of damage position of concrete beam is established.The method of damage position free of models used in this paper is based on the var
Densification, phase transformation and fracture toughness were studied in hot-pressed Si_3N_4 seeded by in-houseproduced large, elongated β-Si_3N_4 seeds. A
The α-SiC in 0.5 μm size powders were coated with Al2O3 and Y2O3 by a coprecipitation coating (CPC) method for fabrication of SiC/YAG composites. The same pow
