ABS Technical Bulletin #11

Composite Chemistry Feature

(released January 25, 1996)

The Alloy Blending System includes the ability to construct a composite chemistry from up to ten (10) existing material records. This option permits you to select the chemistry desired from any existing record.

The composite chemistry feature is available when changing an existing material’s analysis or when entering a new material’s analysis. The examples that follow for the Windows version were obtained from the Inventory Receipts function; the same capability exists when entering or changing materials via the Material Editor program.

When <F6> is pressed when entering a new material’s analysis (or changing an existing material’s analysis), the following dialog will appear:

The toolbar at the top of the screen will display the following options:

<F1> - Display a help message.
<F2> - Display a list of material names on file.
PgUp/PgDn - Display the next (or previous) page of materials.
<F4> - View the details of the highlighted material record.
About - Display documentation file.
<Esc> - Exit or quit change analysis.

The name and lot number of the active (current) receipt/record will appear at the top of the screen. The percent (%) field will be 100.

To begin, select the source file (average, scrap chemistry, or material) for the first material:

Next, enter the name, lot number, and composition percentage for each material you desire to use. To display a list of materials to select from, highlight the material name field and press <F2>.

The expected loss (oil/water) percentage defaults to zero (implying no loss). If any value is entered, it will be subtracted from 100 and saved as the “Material Recovery %”. The composite chemistries shown below were comprised from the following four (4) materials:

 Material A

 Material B

Material C

Material D
 CR=20%  MO=5%  NI=20%  SI=10%
 FE=Balance  NI=10%  MO=Balance  CR=10%
   FE=Balance    NI=Balance
