Influences of strain rate and deformation temperature on flow stress and dynamic recrystalliazation of heat resistant steel P91 Xueqin Jin 1,a, Dasen Bi1,2,b, Jian Zhang1,2,c, Xiaolan Wang1,d, Jianhua Song 1,e, Zhihua Wang1,3,e, 1 School of Materials Science & Engineering, Tianjin University of Technology, Tianjin 300384, China 2 Key Laboratory of Display Materials & Photoelectric Devices (Tianjin University of Technology), Ministry of Education, Tianjin 300384, China 3Tianjin Key Lab for Photoelectric Materials & Devices, Tianjin 300384, China ajinxueqin0622@163.com, btjbds@sina.com, czhang_jian_99999@126.com Keywords: heat resistant steel P91; hot simulation; flow stress; dynamic recrystallization Abstract.
The test curve shows that P91 materials have the dynamic recrystallization and recovery behavior in high temperature and deformation.
It can enhance metal materials thermoplastic in the very great degree [1].
In recent years, heat resistant steel P91 (10Gr9Mo1VNb), as a kind of new materials, has been researched and exploited at home and abroad.

Introduction It has been well accepted that the properties of materials strongly depends on their microstructures.
Gibson and Ashby [5] also found that many natural materials have cells looks and behave like a honeycomb.

But titanium alloy TC4 belongs to the typical difficult-to-machine materials, the thermal conductivity is bad, the chemical activity is high, elastic modulus is small, which directly led to the processing sclerosis serious, low cutting speed, short cutting tool life, and lower processing efficiency.
The experiment tool is three blade solid carbide end mill, materials is YG8, cutting tools length is 65 mm, tool diameter is 10 mm, former angle is γ0=12.5°, spiral angle β=34.5°, cutting part in length is 30 mm.
