1.Then,according to experimental results,it was concluded that the steel slag content was the most important factor to cleavagestrength,which went up with time,and could get the strength,0.14—0.20 MPa after 28 days maintenance.
3.And when the activities of SPS and SS (synthetic direction) increased gradually, that of SS (cleavage direction) rose againcorrespondently, having no invertase when sugar accumulating, SS (cleavage direction) became a key enzyme to regulate sucrose content, which adjusted fruit sink strength.
4.With a detailed understanding of strength in alloys, this lecture begins to address the issue of ductility and toughness. Necking and cleavage cracking are discussed in terms of prior concepts.
5.The results show that the (material) has high strength (σ_(bb)~2200?MPa, σ_(bc)～3000?MPa) and hardness?(HRC 62~68),and higher fracture toughness (~30(MPa·m~(1/2)).) The main fractographic appearances are WC cleavage,quasi-cleavage of matrix,dispersed dimples and dimple bands.
