@article{oai:nagano-nct.repo.nii.ac.jp:00000214, author = {森山, 実}, journal = {長野工業高等専門学校紀要}, month = {Jun}, note = {application, TiN-TiAl ceramics/intermetallic composites containing no additives were hot-pressed from a mixture of TiN, Ti and Al powders containing 5 up to 100massl%TiAl (5, 20, 40, 60, 80, 100mass%TiAl), which were formed from a reaction between Ti and Al. Hot-pressing was conducted at 1000℃ for 7.2 ks under a pressure of 13.9 MPa in an Ar gas atmosphere. The mechanical and electrical properties were examined as a function of compositional change from 5 to 100mass%TiAl. TiN-TiAl composites containing 60~100mass%TiAl had a relative density of 67.3~71.1%, bulk density of 2380~2830kg m^<-3>, Vickers hardness of 506~2771MPa, flexural strength of 50~123MPa, Young's modulus of 45.9~82.4GPa, and electrical conductivity of 606~778k S・m^<-1>. The sufficient densification was not necessarily performed because the reaction from Ti and Al to TiAl phase was not completed by the use of coase Ti and Al powders.}, pages = {65--71}, title = {TiN-TiAl複合体の機械的特性}, volume = {36}, year = {2002} }
