On the Tensile Strength of Spark Plasma Sintered AlMgB₁₄ Ceramics.

ABSTRACT: In this work, the structure, phase composition, hardness and tensile strength of the AlMgB₁₄-based material obtained by spark plasma sintering (SPS) were investigated. According to the XRD results, the spark plasma sintered material contains 94 wt% AlMgB₁₄ phase and 6 wt% spinel MgAl₂O₄. Analysis of the SEM images showed that the obtained AlMgB₁₄ sample has a dense structure; the relative density of the sample is 98.6%. The average microhardness of the spark plasma sintered (SPSed) sample is 29 ± 0.88 GPa. According to the results of the Brazilian test, the tensile strength of AlMgB₁₄ is 56 MPa. The fracture is characterized by a single straight tensile crack that divides the sample along the compression line into two halves
