    摘要： A method of producing a workpiece is disclosed. The method includes: providing a first powder, a hardness of the first powder being less than 250 HV, and a mean particle size of the first powder being less than 20 μm; mixing the first powder and a second powder to form a mixed powder; the mixed powder includes carbon, chromium, iron, and elements selected from the group consisting of molybdenum, nickel, copper, niobium, vanadium, tungsten, silicon, cobalt, and manganese; adding a binder and water to the mixed powder; applying a spray drying process to granulate the mixed powder to form a spray-dried powder; applying a dry pressing process to the spray-dried powder to form a green part; applying a debinding process to the green part to form a debound body; and sintering the debound body into a workpiece having a hardness of higher than 250 HV.

    摘要： The present teaching is generally directed to soft magnetic alloys. In particular, the present teaching is directed to soft magnetic alloys including Samarium (“Sm”). In a non-limiting embodiment, an Sm-containing magnetic alloy is described including 15 wt % to 55 wt % of Cobalt (“Co”), less than 2.5 wt % of Sm, and 35 wt % to 75 wt % of Iron (“Fe”). The Sm-containing magnetic alloy may further include at least one element X, selected from a group including Vanadium (“V”), Boron (“B”), Carbon (“C”), Chromium (“Cr”), Manganese (“Mn”), Molybdenum (“Mo”), Niobium (“Nb”), Nickel (“Ni”), Titanium (“Ti”), Tungsten (“W”), and Silicon (“Si”). The Sm-containing magnetic alloy may further have a magnetic flux density of at least 2.5 Tesla.
