The complex inclusions in CGHAZ promote the acicular ferrite formation, which is associated with heat input and affects the mechanical properties of CGHAZ.
结果表明：CGHAZ中复合夹杂物可促进针状铁素体的形成，针状铁素体的数量与输入线能量有关并显著影响CGHAZ的力学性能。
By using appropriate TMCP process, complex phase of acicular ferrite with different compositions could be obtained in low carbon alloy pipeline steel.
采用合适的TMCP工艺，可以在低碳合金管线钢中获得不同组成比的针状铁素体复相组织。
