lath of martensite的意思|示意

Then the morphology was observed by optical microscope and SEM. The grain size of austenite, the number of martensite in austenite grains and the spacing of the lath martensite were measured.

用金相显微镜和SEM观察了试样铸态微观组织形态，测定了奥氏体晶粒尺寸以及奥氏体晶粒内马氏体板条束个数和马氏体板条间距。

The microstructure of the steel transforms from ferrite plus granular bainite, lath bainite plus lath martensite and then to lath martensite successively with the increasing of cooling rate;

随着冷却速率的增加，实验钢的显微组织由铁素体+粒状贝氏体逐步转变为板条贝氏体+板条马氏体及板条马氏体组织；

The results show that as-annealed microstructure and as-quenched-tempered microstructure of the low carbon high alloy steel added nickel are both single-phase lath martensite.

结果表明：加镍低碳高合金钢无论退火态还是淬火回火态，其组织均为单相板条马氏体；

Experiments show that the dual phase structure suitable to wire drawing consists of fine ferrite islands dispersed in the matrix of lath martensite.

实验表明，适于拔丝的双相组织是在板条马氏体基体上分布着细小的铁素体岛。

The microstructure of surfacing metal is lath martensite and carbide.

堆焊层显微组织为低碳马氏体和碳化物。

The results indicated that the steel is composed of quasi bainite, lath martensite and twin martensite under air cooling condition, and also has better combination of strength and toughness.

试验表明：该钢空冷条件下即可获得准贝氏体、板条马氏体及孪晶马氏体的复合组织，且具有较好的强韧性配合。
