COMPOSITION TRIANGLE DIAGRAMS OF Ni-Mn-Ga MAGNETIC SHAPE MEMORY ALLOYS H.B. Xu1,J.M. Wang1,Y.F. Wang1,C.B. Jiang1 (1.School of Materials Science and Engineering, Beijing University of Aeronautics... (Ms), large magnetostrain or the co-existence of magnetic and structural transitions. The alloys with five-layered ( 5M), seven-layered(7M) modulated and non-modulated (T) martensitic structures were......
performance than HS-b in the practical application for pelletizing of iron concentrates. The difference in agglomeration behaviors with iron concentrates lies in the differences of the structure characteristics of HSs. With higher content of polar functional groups, larger relative molecular mass and viscosity of HSs, the agglomeration behavior is improved. Key words: humic substances; structure......
