Abstract
เหล็กกล้า (steel) มีองค์ประกอบทางเคมีที่ประกอบด้วย 0.050% ถึง 0.40% ของ C, 0.50% ถึง 3.0% ของ Si, 3.0% ถึง 8.0% ของ Mn, และ 0.001% ถึง 3.0% ของ sol. Al, โดย % โดยมวล, และ มีโครงสร้างทางโลหะวิทยาที่ประกอบด้วย 10% ถึง 40% ของออสทีไนต์เกี่ยวกับ % โดยปริมาตร ความเข้มข้นเฉลี่ยของ C ในออสทีไนต์เป็นระหว่างเป็นระหว่าง 0.30% ถึง 0.60%, โดย %โดยมวล, การเป็น หนึ่งเดียวกันของโครงสร้าง, ซึ่งถูกแทนโดยค่าที่ได้รับโดยการลบค่าต่ำสุดจากค่าสูงสุดของความ แข็งวิกเกอร์สที่ถูกวัด, ในโครงสร้างทางโลหะวิทยาเป็น 30 Hv หรือน้อยกว่านั้น, และความทนต่อ แรงตึงเป็น 900 เมกะพาสคาล ถึง 1800 เมกะพาสคาล Steel has a chemical composition comprising 0.050% to 0.40% of C, 0.50% to 3.0% of Si, 3.0% to 8.0% of Mn, and 0.001% to 3.0% of sol.Al, by mass%, And has a metallurgical structure containing 10% to 40% of austenite.About% by volume, the average C concentration in oustenite is between 0.30% and 0.60%, by% by mass, The unity of the structure, which is represented by the value obtained by subtracting the minimum from the maximum of the The measured Vickers hardness, in metallurgical structures is 30 Hv or less, and the tensile strength is 900 Mpa to 1800 Mpa.
