Hello everyone,

I want to simulate the alpha-Ti (hexagonal) participating from beta-Ti (cubic) considered the stress.

I get the elastic constant c11, c12, c13, c33 and c55 of alpha-Ti, but only c11, c12 and c44 can be set for alpha-Ti (hexagonal).

The detail settings were shown as follows:

......

# Data for phase 2:

# -----------------

# [identical phase number]

# Simulation of recrystallisation in phase 2?

# Options: recrystall no_recrystall [verbose|no_verbose]

no_recrystall

# Is phase 2 anisotrop?

# Options: isotropic anisotropic faceted antifaceted

anisotropic

# Crystal symmetry of the phase?

# Options: none cubic hexagonal tetragonal orthorhombic

hexagonal

# Should grains of phase 2 be reduced to categories?

# Options: categorize no_categorize

# The database contains 3 phases:

# 1: BCC_A2

# 2: HCP_A3

# 3: LIQUID

# Specify relation between phase indices Micress -> TC!

# The matrix phase has in MICRESS the index 0

Is there anything wrong in my setting?

Hi wzb198910,

The current MICRESS version does not allow usage of non-cubic elastic data. We are sorry for that...

Best wishes
