Abstract(E)Low density steel sheets can exhibit super-plasticity properties under characteristic composition and process conditions, so they can be applied to large-sized plate parts with high forming difficulty based on high elongation in a single press process, which has the advantages of process simplification (welding deletion, etc.) and mold reduction. We designed various compositions of Fe-Mn-(Al-Si)-C low-specific-weight steel sheets, evaluated super-plasticity properties, analyzed the cause of its occurrence, and verified the properties at room temperature in consideration of future part applicability

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
