“…Ferritic stainless steel is noted for its excellent stress corrosion cracking resistance, good plasticity and toughness, high thermal conductivity and small linear expansion, which has been widely applied as corrosion resistant material in the modern industries [1].Furthermore, it is characterized of lower cost by comparison with austenite stainless steel, which makes it good substitute for austenite stainless steel. However, its low strength cannot meet the high requirement for mechanical properties, which restricts its widespread application [2]. Therefore, it has been noticed to improve the strength of ferritic stainless steel.…”
