Environmental media used in this study were vacuum, air, water vapor, a mixture gas of 5 vol%H<sub>2</sub>+Ar, O<sub>2</sub> gas, N<sub>2</sub> gas and Ar gas. All the TiAl-based intermetallic alloys showed low tensile strength or tensile elongation in air, water vapor and a mixture gas of 5 vol%H<sub>2</sub>+Ar compared to those in vacuum. The reduction of tensile strength or tensile elongation (i.e. environmental embrittlement) was observed not only in low temperature range mostly reaching 600 K but also in high temperature range mostly from 600 K to 1000 K (sometimes temperatures higher than 1000 K). The low- and high-temperature environmental embrittlement depended on the alloy composition (or microstructure). The low-temperature environmental embrittlement diminished at higher strain rates. The high-temperature environmental embrittlement diminished not only at higher strain rates but also at lower strain rates. The possible species causing the high-temperature environmental embrittlement is hydrogen atoms decomposed from water vapor (H<sub>2</sub>O) or hydrogen gas (H<sub>2</sub>), similar to those causing the low-temperature environmental embrittlement. Also, it is suggested that the oxidized scale is effective in reducing the high-temperature environmental embrittlement."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420001326232420736","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"50214482"},{"@type":"NRID","@value":"1000050214482"},{"@type":"NRID","@value":"9000000496408"},{"@type":"NRID","@value":"9000020656206"},{"@type":"NRID","@value":"9000006399180"},{"@type":"NRID","@value":"9000304309088"},{"@type":"NRID","@value":"9000380476948"},{"@type":"NRID","@value":"9000283876946"},{"@type":"NRID","@value":"9000356895741"},{"@type":"NRID","@value":"9000257968215"},{"@type":"NRID","@value":"9000017329083"},{"@type":"NRID","@value":"9000331909562"},{"@type":"NRID","@value":"9000404340519"},{"@type":"NRID","@value":"9000257838860"},{"@type":"NRID","@value":"9000361678388"},{"@type":"NRID","@value":"9000256207415"},{"@type":"NRID","@value":"9000398165751"},{"@type":"NRID","@value":"9000321622748"},{"@type":"NRID","@value":"9000345194291"},{"@type":"NRID","@value":"9000257969333"},{"@type":"NRID","@value":"9000241627641"},{"@type":"NRID","@value":"9000256206569"},{"@type":"NRID","@value":"9000392797921"},{"@type":"NRID","@value":"9000398990695"},{"@type":"NRID","@value":"9000257845564"},{"@type":"NRID","@value":"9000001815233"},{"@type":"NRID","@value":"9000404153157"},{"@type":"NRID","@value":"9000313610427"},{"@type":"NRID","@value":"9000402022877"},{"@type":"NRID","@value":"9000404102060"},{"@type":"NRID","@value":"9000398167509"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0020963"}],"foaf:name":[{"@language":"en","@value":"KANENO
