The effects of processing parameters of ferritic rolling on microstructures and mechanical properties especially on deep drawability of ultra-low carbon and Ti-stabilized interstitial-free steels were investigated,and the precipitates in Ti-IF steel were also analyzed.

The cross-section metallurgic structure at various annealing temperature is analyzed and compared with import material based on the statistical study of the influence of annealing temperature on the deep drawability of cold rolled IF steel.

The effect of the reduction in cold rolling IF steel sheet for drawability;

The results showed that the IF steel has better deep drawability,higher mechanical and texture strength and elongation if the hot rolling temperature was low with big reduction in ferrite region.

How the processing conditions affect the properties especially the drawability of a ferritic hot-rolled and annealed Ti-IF sheet steel was investigated.

Effect of cold rolling-process on microstructure and deep-drawing property of 1050H19 aluminum foils used in air-conditioner;

The relationship of deep-drawing property and rolling parameters of IF steel was researched by the testing of ferritic rolling and annealing.

Influence of texture in 3104 Aluminum sheet on r values and deep drawing property;

Functional relationship between deep drawing property and process parameters of Zn-Cu alloy was studied by regression analysis method.

After being rolled in ferrite area, the IF steel was proceeded once and twice cold rolling, then its deep drawing property was studied.

Under the laboratory condition,by the precipitate observation,the precipitate behavlour of IF-HSS was investigated a new precipitate TiFeP was discovered,and effect of P element in steel on deep drawing properties was further discussed.
