Dendrite Arm Spacing

Dendrite Arm Spacing measures the spacing between adjacent dendrite arms.
By using pre-set interval values, this software can automatically calculate the secondary

dendrite arm spacing through the intercept method.
The measurement results are summarized into an easy-to-read spreadsheet format.

MEASUREMENT The measured results are recorded in real time on  the measurement table. For each measurement, the minimum, maximum, mean, and standard deviation of ARM (µm) spacing are calculated and listed in the table. STATISTICS Basic statistics are automatically listed in the STATISTICS section: Mean spacing Minimum spacing Maximum spacing Standard deviation REPORT By pressing the REPORT button, the results are transferred to Excel and can be managed as documentation.

Key Features

• Average dendrite arm spacing determination

• Evaluation of each intercept line: measured distances and number of dendrites

• Automatic result spreadsheet generation

• Purpose: To measure the spacing between adjacent dendrite arms

• Measurement method: Automatic measurement (intercept method with pre-set interval setting)

• Report / OutputReport / Output: Spreadsheet (spacing data, mean dendrite arm spacing [µm]), overlay image (spacing measurement overlay)

Setup

At the beginning, the user sets an appropriate interval value for dendrite spacing measurement.
During measurement, the user must draw an intercept line across the dendrites, and the system will automatically calculate the spacing while counting the number of dendrite arms.
The drawn line should be placed in a representative area of the entire structure, and each line should include several dendrite arms for statistical reliability.

Operation

The system accurately calculates the spacing between dendrite arms based on the intercept line drawn by the user.
Each intercept line is evaluated, and the measured distances, number of dendrites, and intervals are displayed.
Before the next evaluation begins, the measured values are stored in the spreadsheet.

Results

The calculated dendrite arm spacing results are stored in a spreadsheet format.
The results include:

• Measured distances

• Mean spacing

• Minimum spacing

• Maximum spacing

• Number of dendrites per intercept line

These results allow users to analyze spacing distribution across the microstructure.
By combining multiple intercepts, DAS results can be summarized into overall statistical values with higher reliability.
