magnetic aging

combining with the quality control level of high-quality magnetic iron of taigang and the test methods of magnetic aging, improving process of artificial aging was put forward.

阐述了电磁纯铁的磁时效现象及其机理，并结合太钢无磁时效优质电磁纯铁的质量控制水平和磁时效检验方法，提出了人工时效处理的改进工艺。

High magnetic field possesses revolution, orientation and gathering action for tissue of Al-4% Cu alloy aging. When magnetic field strength is enlarged, the action is built up and accumulative banding precipitated phases become black and long.

研究还发现强磁场作用使Al-4%Cu合金时效析出组织具有明显的旋转取向和聚集效应，随着磁场强度的增大，这种旋转取向和聚集效应增强，聚集的条状析出相呈黑，长形态。

carbon is an important element that causes magnetic aging of silicon steel and as the carbon content in the silicon steel increases, the iron loss also increases, but with increase of silicon, the iron loss decreases obviously.

其中碳是引起硅钢发生磁时效的重要元素之一，随着硅钢中碳含量的增加，其铁损增加；而硅含量增加能显著降低硅钢铁损。

magnetic aging, powder, the rod is not enough material.
