    Abstract: A process is provided for preparation of an aluminum-killed medium-carbon steel sheet containing by weight from 0.040 to 0.080% of carbon, from 0.35 to 0.50% of manganese, from 0.040 to 0.070% of aluminum, from 0.004 to 0.006% of nitrogen, the remainder being iron and the inevitable trace impurities, wherein the steel contains carbon in free state, a grain count per mm2 greater than 20000 and, in the aged condition, has a percentage elongation A % satisfying the relationship: (640nullRm)/10nullA%null(700nullRm)/11 where Rm is the maximum rupture strength.

    Abstract: A metallic sheet with an aluminum coating, the coating having an internal layer of iron/aluminum/silicon alloys, and an external layer, thicker, of an aluminum-based phase and secondarily of phases in the form of needies or elongated lamellae. The projection of the length of all needles or lamellae in a direction perpendicular to the plane of the external layer is less than the thickness of this layer. This structure, which is obtained by a thermal treatment of the external layer at a temperature of 570-660null C. notably for less than 15 sec, considerably decreases the risks of cracking.

    Abstract translation: 具有铝涂层的金属片,所述涂层具有铁/铝/硅合金的内层,以及外层,较厚的铝基相,其次为需要或细长片状的相。 所有针或薄片在垂直于外层平面的方向上的长度的投影小于该层的厚度。 通过在570-660℃,特别是小于15秒的温度下对外层进行热处理而获得的这种结构大大降低了开裂的风险。
