Ramework materials as a result of its preparation method. framework materials, pre-alloyed powders and pre-alloyed powder enhanced, the With the increase of Ni content, the proportion ofdiamonds. Diamonds are brazed inso the framework materials employing the pre-alloyed powder as a bonding phase. The pre-alloyed hardness of sintered matrix enhanced. Secondly, together with the boost of Ni, the loss of liquid powder has larger hardness than the framework components due to its preparation process. phaseWith the increase of melting point material is lowered and more liquid phaseso the developed by low Ni content material, the proportion of pre-alloyed powder elevated, fills the gaps amongst the powders, thus elevated. Secondly, with theincrease.of Ni, the loss of liquid hardness of sintered matrix the density and hardness increasephase developed by low melting point material is reduced and more liquid phase fills the gaps among the powders, as a result the density and hardness increase.one hundred 95 Hardness (HRB) 90 85 80 75 0 three 6 9 Ni (wt.) 12Figure 5.

However, the Ni content exceeds 9 wt. , the melting point of Fe-Cu-Sn-Ni-Zn is improved as well as the loss of liquid phase is decreased, thus the excessive Cu3Sn phase forms, as well as the bending strength and shearing strength in the sintered matrix decreases slightly.Figure six shows the bending strength and shearing strength of sintered matrixes with distinctive Ni contents. The bending strength and shearing strength is 367 MPa and 573 MPa Figure 6 shows the bendingWith the boost of Ni, the bending strength and shearing without having Ni within the powders. strength and shearing strength of sintered matrixes with strength increases. When the strength is from 3 to 9 wt. , the bending strength and distinctive Ni contents. The bendingNi contentand shearing strength is 367 MPa and 573 MPa shearing the powders. With all the boost of content bending strength and shearing with out Ni in strength enhance swiftly. Even though the Ni Ni, the exceeds 9 wt. and elevated to 15 wt. , the bending strength and shearing strength decreases the bending strength and strength increases. When the Ni content is from 3 to 9 wt. , slightly. Some paper note that the hardness, bending strength and shearing strength is closely shearing strength increase rapidly. Though the Ni content exceeds 9 relevant to the density to wt. and improved for powder metallurgy, meanwhile, these values increase with the improve of density [20]. 15 wt. , the bending strength and shearing strength decreases slightly. Some paper note When the Ni content increases, the reduction of liquid phase loss leads to more liquid that the hardness,the gap among the and shearingthe hardness closely relevant to the density phase filling bending strength powder, hence strength is enhance and bending strength for powder metallurgy, meanwhile, also improve. increase using the improve thedensity [20]. together with shearing strength these values Furthermore, Figure two shows of grain size Whenbecomes content with the raise of Ni content material and compounds of Cu3 Sn phase as well as the Ni smaller sized increases, the reduction of liquid phase loss results in a lot more liquid phaseCu5 Zn8 phase are progressively fine and dispersed.
